努力开发公式，以对比在社会Hypltera的工人和皇后的遗传利益是复杂的许多因素，包括多次交配的皇后，产卵的未交配的女性，和交配竞争之间的遗传亲属（汉密尔顿的“本地配偶竞争”）。由于单倍二倍体的性别决定在Hyattera，当这种影响是缺席的，皇后受益于1：1的性别比例的投资（男性：女性）在生殖后代，工人从1：3的比例之间的生殖同胞。报告的可变比率，包括许多远高于1：3，和女性的偏见，在非社会Hyattera和二倍体白蚁，牵连当地的配偶竞争，并提出了问题，以前的解释，工人有自己的方式。
Efforts to develop formulas for contrasting genetic interests of workers and queens in social Hymenoptera are complicated by many factors, including multiple matings by queens, oviposition by unmated females, and mating rivalry among genetic relatives (Hamilton's "local mate competition"). Because of haplodiploid sex determination in Hymenoptera, when such influences are absent, queens benefit from 1:1 sex ratios of investment (male: female) in reproductive offspring, workers from 1:3 ratios among reproductive siblings. Reports of variable ratios, including many well above 1:3, and female biases in nonsocial Hymenoptera and diplodiploid termites, implicate local mate competition and raises questions about previous interpretations that workers have their way.
